L-Dopachrome
Dopachrome is a cyclization product of L-DOPA and is an intermediate in the biosynthesis of melanin. Dopaquinone has an ortho-quinone ring, which is known to be neurotoxic and highly reactive with many other compounds (PMID: 413870). Dopachrome spontaneously gives rise to 5,6-dihydroxyindole (DHI) or it can be enzymatically metabolized by dopachrome tautomerase to give 5,6-dihydroxyindole-2-carboxylic acid (DHICA). DHI and its oxidation products are also toxic to cells. Many Parkinsons patients are treated with L-DOPA. However, long-term treatment with L-DOPA may actually worsen symptoms or may result in neurotic and psychotic symptoms. These may be due to dopachrome and dopaquinone accumulating in the brain of L-DOPA treated patients (PMID: 19131041, PMID: 12373519). The non-decarboxylative tautomerization of L-dopachrome to 5,6-dihydroxyindole-2-carboxylic acid in the melanin biosynthetic pathway is catalyzed by Tyrosinase-related protein-2, a melanocyte-specific enzyme.

D-Dopachrome
D-dopachrome is reversibly converted into 5,6-dihydroxyindole and carbon dioxide via the enzyme D-dopachrome decarboxylase (EC 4.1.1.84). Cultured human melanoma cells contain this enzyme as well as human liver (PMID: 8267597). Dopaquinone has an ortho-quinone ring, which is known to be neurotoxic and highly reactive with many other compounds (PMID: 413870). D-dopachrome is reversibly converted to 5,6-dihydroxyindole and carbon dioxide via the enzyme D-dopachrome decarboxylase (EC 4.1.1.84).
